Tailoring SHG Efficiency via t‐Te Nanocrystals in Tellurite Glasses by Femtosecond Laser Micromachining

Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
Femtosecond laser irradiation at the glass surface induces symmetry breaking and crystallization of triclínic t‐Te nanophases, enabling intense second‐harmonic generation (SHG). The illustration depicts the fs‐pulse interaction, structural rearrangement, and nonlinear activation from amorphous tellurite glass to crystalline regions.

New Hybrid Nanocomposite Films for Optical Diagnostics and Optical Temperature Sensing: Synergy Among α‐Synuclein, Gold and Upconverting Nanoparticles

Small, Volume 22, Issue 15, 12 March 2026.
Gold and upconverting nanoparticles coated with alpha‐synuclein were exploited to produce a quasi‐monolayer hybrid film. The film was then characterized, and its behaviour as a primary optical nano‐thermometer was studied. The film was also used in a proof‐of‐concept study of image‐based optical nanothermometry exploiting a home‐built up‐conversion ...

f‐Block Element‐Based MOF Thin Films: A Platform for Luminescence, Sensing, and Energy Applications

Small, Volume 22, Issue 16, 17 March 2026.
f‐Block element–based metal–organic framework (f‐MOF) thin films offer exceptional potential for luminescent, sensing, and energy‐related applications. This review surveys recent progress in their synthesis, characterization, and functional implementation, emphasizing the diversity of available thin‐film fabrication strategies. The convergence of these

Effect of Ce/La Substitution on Optical Transparency and Ionic Conductivity of Sodium Silicate Glasses

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT We investigate sodium silicate glasses modified with Ce2O3 and La2O3 to explore the interplay between optical absorption, structure, and macroscopic properties. Ce doping drives a pronounced red‐shift of the absorption edge into the visible region (> 500 nm), arising from O2− →$ \to $ Ce4+ charge‐transfer and intervalence transitions ...
